Problema Solution
The width of a rectangle is 8 less than twice its length. If the area of the rectangle is 174 square centimeters, what is the length of the diagonal?
Answer provided by our tutors
Let 'w' and 'l' stand for the width and length of the rectangle. We can write:
w=2l-8 ('The width of a rectangle is 8 less than twice its length.')
wl=174 ('the area of the rectangle is 174 square centimeters')
diagonal= square root of (l^2+w^2)
Solving for the diagonal, we get:
diagonal=13.19 cm
